"Get at who?" Marco asked suspiciously.

"The French, Marco," I said sarcastically. "Who do you think? The Yeerks, duh."

"Whoa, whoa, whoa!" Marco said. "We tried that, remember? We went down into the Yeerk pool after them and got our butts kicked. Yeerks ten, humans zero."

... "We gave them a reason to be afraid at least."

"Yeah, they're terrified of us. Visser Three probably can't sleep at night, he's so worried about five kids," Marco said sarcastically. "Look, Visser Three doesn't think we're a threat. He thinks we're lunch."
